TECHNICAL FIELD

Exemplary embodiments of the present invention relate generally to an apparatus and system for mounting an electronic display to the roof of a vehicle.

BACKGROUND AND SUMMARY OF THE INVENTION

Vehicle toppers are sometimes used to display information and advertising on the otherwise vacant roof of a vehicle. For many years, these vehicle toppers displayed static images. In recent years, electronic displays have replaced traditional, static displays. The use of electronic displays allows content to be quickly and easily changed and permits the use of videos and interactive graphics, among other benefits. However, these electronic displays often require additional equipment, making them heavier than their traditional counterparts. Further, the market has begun demanding increasingly larger displays, which requires increasingly larger (and generally heavier) vehicle toppers. Those of skill in the arts of placing displays on the roofs of vehicles have believed that it was necessary to provide vehicles carrying such electronic displays with drastic, enhanced internal structural supports to enable a relatively heavy and large electronic display to be mounted to the roof of the vehicle in a secure manner. Theses enhanced internal structural supports require significant effort and costs to install. Additionally, such modifications typically require significant effort to remove and leave lasting changes to the vehicle, if removal is even possible. As an example, but not to serve as a limitation, one may wish to remove the display so that one can resell a vehicle and/or place the display on a different vehicle.

With the rise of private transportation service companies such as Uber and Lyft, personal vehicles are increasingly being used for paid transportation services alongside more traditional services such as public transportation, taxis, town cars, and limousines. Such private or commercial drivers, or any other owner of a personal or commercial vehicle, could benefit from being able to display advertisements and other information on a vehicle topper that is capable of being mounted to a personal or commercial vehicle without the need for extensive modification. Such a vehicle topper can be used to display information and advertising for a multitude of purposes, including but not limited to, generating additional revenue for the vehicle owner or driver. Therefore, what is needed is a roof mounting apparatus and system for a vehicle topper having an electronic display.

Roof mounted objects, such as but not limited to vehicle toppers, often experience vibrational forces. Such forces may be caused by traveling over bumpy, rough surfaces, or uneven road surfaces, aerodynamic forces, and/or the vehicle itself (e.g., engine vibrations). Such vibrational forces may be translated through the frame and other components of the vehicle to the vehicle topper. Exposure to prolonged or excessive vibrational forces may cause the damage to the vehicle topper or even cause the vehicle topper to become dislodged. Vehicle toppers are likely to experience a number of forces when the vehicle is in operation. In order to stably mount the vehicle topper unit to the vehicle, enhanced strength mounting components are needed. Additionally, components which dampen or otherwise attenuate the transfer of vibrational forces are desirable. Therefore, what is needed is roof mounting apparatus and system for a vehicle topper having an electronic display, where said roof mounting apparatus and system dampens or otherwise attenuates vibrational forces and has enhanced strength mounting components.

The present invention is a roof mounting apparatus and system for a vehicle topper having an electronic display, where said roof mounting apparatus and system dampens or otherwise attenuates vibrational forces and has enhanced strength mounting components. The vehicle topper may comprise a pair of displays placed back to back. The vehicle topper may have a mounting device for securing the vehicle topper to a pair of cross bars. The cross bars may be attached to a set of base units located at substantially the four corners of the vehicle roof. The front pair of base units may be located near the A pillar while the rear pair of base units may be located near the C pillar.

Each base unit may be mounted to the roof by a pair of threaded fasteners that extends through the cross bars and the base units and into rivet nuts placed in the roof, such as in the rain ditch. The threaded fasteners and rivet nuts may provide a substantially watertight seal. The bottom surface of the base units may be configured to match the pitch of the roof for each model and make of car such that the bottom edge of the vehicle topper, when mounted, is located substantially parallel with the ground and approximately ¼^(th) inch above the crown point of the roof. Wiring may extend from a power source, the other electronic components for operating the vehicle topper, and the vehicle's computer system, each of which may be located in the trunk or beneath the hood of the vehicle, to the vehicle topper. The wiring may travel through or along the A, B, or C pillars, the base units, the cross bars, and to or into the vehicle topper.

The cross bars may be comprised of sufficiently strong materials and of be of sufficient thickness to adequately support the vehicle topper. The cross bars may comprise a varying cross section. The varying cross section may cause the cross bar to have different natural or resonant frequencies at different locations, as the cross section may affect the cross bar's natural or resonant frequency. In exemplary embodiments, the cross bars may taper from the outer edges towards the center. A center section of the cross bay may have a consistent cross section. The center section may be utilized for attaching the vehicle topper to the cross bar. The cross bars may be configured to receive wiring, which may extend therethrough. The cross bars may additionally be configured to receive caps on the outer ends thereof to improve appearance and aerodynamics.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENT(S)

Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the following description, specific details such as detailed configuration and components are merely provided to assist the overall understanding of these embodiments of the present invention. Therefore, it should be apparent to those skilled in the art that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

FIG. 1A and FIG. 1B illustrate an exemplary mounting apparatus for mounting an exemplary vehicle topper 10 to a roof 21 of a vehicle 20. A number of base units 26 may be located on the roof 21. A pair of cross bars 24 may extend across the roof 21, each between two of the base units 26. The cross bars 24 may be comprised of tube steel and may comprise a substantially square, rectangular, or tubular cross section, though any shape is contemplated. In other exemplary embodiments, the cross bars 24 may be formed by folding sheet metal into a substantially C-shaped bar, though any manufacturing process is contemplated. As further described herein, in other exemplary embodiments, the cross bars 24 may comprise a varying cross section. The cross bars 24 may be comprised of a metal or a blend of metals, though any material is contemplated.

A first and second cross bar fascia 23 may be attached to each of the cross bars 24. Each cross bar fascia 23 may cover a portion or substantially all of the respective cross bar 24. The cross bar fascia 23 may provide an aesthetically pleasing look as well as improved aerodynamics. As an example, but not to serve as a limitation, the cross bar fascia 23 may be shaped to substantially match the curve of the roof 21. The cross bar fascia 23 may be comprised of plastic, though any type of material is contemplated. In exemplary embodiments where a substantially C-shaped cross bar 24 is utilized, the cross bar fascia 23 may additionally enclose the otherwise open end of the C.

The base units 26 may be configured to be located near each corner of the roof 21. In this way, the first cross bar 24 may extend between the pair of base units 26 mounted near the front of the roof 21 and the second cross bar 24 may extend between the pair of base units 26 mounted near the rear of the roof 21. In exemplary embodiments, the front pair of base units 26 may be placed substantially directly over, or otherwise in close proximity with, the A pillar 16 of the vehicle 20, while the rear pair of base units 26 may be placed substantially directly over, or otherwise in close proximity with, the C pillar 18 of the vehicle 20. This arrangement may assist with decreasing or distributing shock, stress, strain, vibrations, and other forces on the vehicle topper 10 and the roof mounting apparatus.

The base units 26 may be any size or shape and may be configured to be attached to the roof 21. For example, but not to serve as a limitation, the bottom of the base units 26 may be sized and shaped to substantially match the pitch of the roof 21 in the location the base units 26 are to be mounted. The base units 26 may be the same size, shape, and configuration for many or all types of vehicles 20. In other exemplary embodiments, however, the base units 26 are sized, shaped, and configured to fit a particular make and model of vehicle. Each base unit 26 (e.g., the front left, front right, rear right, and rear left) may be differently sized, shaped, and configured or they all may be substantially the same. In exemplary embodiments, the front left and front right base units 26 are substantially identical while the rear left and rear right base units 26 are likewise substantially identical.

The vehicle topper 10 may comprise one or more electronic displays 12. In exemplary embodiments, the vehicle topper 10 comprises a pair of electronic displays 12 placed back-to-back within a housing 11. The components used to operate and maintain the electronic displays 12 may be mounted between, or on the posterior surface of, the electronic displays 12. Such components may include, but are not limited to, electronic storage devices, processors, input/output devices, TCON, video players, other electronic components, fans, thermoelectric units, thermal plates, heat exchangers, cooling channels, plenums, air pathways, other cooling systems, wireless transmitters and receivers, cellular network devices, other communications equipment, GPS, other location detection equipment, temperature sensors, ambient light sensors, air quality sensors, accelerometers, strain sensors, other sensors, cameras, video and imaging capturing equipment, microphone and other audio capturing equipment, speakers, and the like.

In exemplary embodiments, the housing 11 is the same size regardless of the make or model of the vehicle 20 and the housing 11 may be sized to comply with the city ordinances of all cities or a selection of cities. In such embodiments, a standard size display 12 may be used across many vehicle toppers 10. However, in other exemplary embodiments, the housing 11 may be various sizes to accommodate various make and model vehicles 20 as well as various size displays 12.

The vehicle topper 10 may mounted to the cross bars 24 by way of a mounting device 30 located on the vehicle topper 10. In exemplary embodiments, the mounting device 30 may be a pair of brackets that each extend substantially parallel with the ground from the front and the rear ends of the vehicle topper 10. The mounting device 30 may be positioned such that when the vehicle topper 10 is mounted to the roof 21, the bottom edge of the vehicle topper 10 rests a distance from the crown point of the roof 21. For example, but not to serve as a limitation, there may be substantially a ¼ inch gap between the crown and the bottom edge of the vehicle topper 10, though any size gap (or no gap) is contemplated. In this way, the bottom edge of the vehicle topper 10 may rest near the roof 21 of the vehicle 20, thus permitting the vehicle topper 10 to maintain a low profile, which may provide enhanced stability, safety, and aerodynamics as well as providing a more aesthetically pleasing look. Regardless, the mounting device 30 may extend over the top of or surround a portion (or all) of the cross bars 24 and may be attached or bonded thereto such as, but not limited to, through the use of fasteners, bolts, screws, nails, adhesive, welding, or the like. In other exemplary embodiments, the mounting device 30 may comprise a protrusion that interacts with a corresponding groove in the cross bars 24. Any attachment mechanism is contemplated.

A pair of end cap fascia 28 may be configured to be secured to the front and rear of the vehicle topper 10, respectively. The end cap fascia 28 may cover a portion or the entirety of the respective end of the vehicle topper 10 and may also cover at least a portion of the mounting device 30. The end cap fascia 28 may protect the interior of the vehicle topper 10 as well as provide an aesthetically pleasing look and improved aerodynamics. The end cap fascia 28 may be configured to abut or extend atop a portion of the cross bar fascia 23 to present a seamless, unified, or otherwise aesthetically pleasing appearance that may also improve aerodynamics.

The roof mounting apparatus and its various components may be configured to place the bottom edge of the vehicle topper 10 substantially parallel with the ground. Oftentimes, certain vehicles 20 are configured to tilt slightly upwards or downwards when the vehicle 20 is empty of all passengers and cargo. In such cases, the roof mounting apparatus and system as well as its various components may be configured to compensate for said tilt such that the bottom edge of the vehicle topper 10 is mounted substantially parallel with the ground when the vehicle 20 is empty. Alternatively, the roof mounting apparatus and system as well as its various components may be configured to compensate for said tilt such that the bottom edge of the vehicle topper 10 is mounted substantially parallel with the ground when the vehicle 20 is carrying an average load or is substantially fully loaded. This arrangement may reduce shock, stress, strain, vibrations, and other forces placed on the vehicle mounting apparatus, its various components, and the vehicle topper 10 as well as improve overall ride performance of the vehicle 20.
